Sound permeates our daily existence, shaping our experiences and interactions with the world. From the gentle rustle of leaves in the wind to the melodious chirping of birds at dawn, the sound is an integral part of the human sensory experience.
Amidst the symphony of sounds surrounding us lies a fascinating concept known as the “terminal velocity of sound.” Coined by physicist Driss El Fadil, this concept delves into the maximum velocity that sound can achieve under specific conditions.
Just as objects reach a terminal velocity when the force of gravity is balanced by resistance, sound waves too can attain a point where their velocity stabilizes under certain atmospheric conditions.
